OIL BURNER.

Application filed March 29, 1926. Serial No. 98,379.

This invention relates to oil stoves. In oil stoves of the usual construction in which burners are supplied by oil irom a reservoir through the medium of a main s1 1p- 7 For example, it is the usual practice to provide burners having open tops, such for in stance, as that disclosed in the patent to Brennan No. 1,l5l,265 of May 8, 1923, and to supply these burners from a main supply pipe. Obviously, it is imperative to maintain the correct level of the oil under all. conditions irrespective of irregularities in the floor level.

This invention is designed to overcome the difficulties noted above, and objects of this in vention are to provide a novel form of oil stove in which the accurate alignment of the burners, when in operative position, is assured, and in which means are provided for taking care of any floor irregularities. For example, when it is considered that these burners are frequently placed in houses where irregularities in the floor exist, such for instance, as summer cottages, it is apparent that this invention fulfills, a long felt want in this field.

Further objects of this invention are to provide a very simple construction which is easily produced and-easily adjusted.

Embodiments Oil this invention are shown in the accon'ipanyin r drawings, in which:

Figure 1 is airont elevation partly broken away of an oil stove.

Figure 2 is a diagrammatic View of a modified form of the invention.

Referring to the drawings, it will be seen that the oil stove is provided with the usual frame work 1 terminating in bottom feet.

These feet are provided with fittings 2 each 5 of which is equipped with a threaded aperture. An adjusting screw 3 is threaded through this aperture and carries a-dish like foot 4 which may,'if desired, be fluted at its edges as indicated on the right hand side of Figure 1 where the full line showing is dis closed. Preferably, these feet 4: have a dome like bottom.

The oil stove is provided with asupply tank 5 which may comprise a main inverted reservoir 6, preferably 01 glass. This reserveir is equipped with a flange i and a main upper portion oi the cup the bottom edge of the neck 9.

receiving cup 8 carries this flange and allows the neck 9 oi the reservoir to be spaced a slight distance from the bottom of such cup. Preferably, apertures 10 are formed in the to provide free com munication with air. will discharge from the reservoir 6 until turther flow is arrested by the oil coming to v This provides a constant oil level indicated at 11 in Figure 2 which is maintained by replenishing the oil "from the reservoir 6 in an automatic manner.

v A main supply pipe 12 extends horizontally through the stove and communicates with the bottom of the cup 8 by means of a restricted opening 8 as shown in Figure 2. Thismain supply pipe furnishes a plurality of branch pipes 13 whichpass to the respective burners 14;. These burners may be of: any desired type, for instance, as disclosed in the above noted patent, and may be pro vided with adjustable burner drums 15. The burners 141; are adapted to be raised and lowcred, such burners occupying the lowered positions when in operation. The purpose of the opening 8 of restricted size is to permit an adequate flow of oil to supply all of the burners. However, if for instance, the main tank 8 should become flooded as by the breaking or the container 6. a sudden rush of oil to the burners would be checked by the restricted opening 8".

The supply pipe 12 extends horizontally through the stove and projects beyond the side thereof. It is provided at this point with a short standpipe or branch pipe 16 which carries a level indicating cup 01' drum 1'? at its upper end. This drum is provided with an inwardly pressed head 18 and with openings 19. A transparent cap 20 closes the upper end of this leveling drum or compartment.

It is tobe noted that the bottom of the opening 19 is along the line 19, and this line is a slight distance below the top of the burners. In actual practice one-eighth of an inch has been found satisfactory for this spacing. Obviously, therefore, it is impossible to cause the burners to overflow for any reason whatsoever for the reason that the oil will find its way out through the-openings 19 before overflowing; the burners, and consequently, the

safety is the stove is materiallyincreased. It is to be understood also that the cup 17 may stop at the line 19 if desired, and may be open, although the term shown is prefer Obviously, the fuel extreme end of the pipe 12,

able. Further it is to be noted that although the cup 17 may be set within the outline of the stove if desired.

In operation, the stove is set upin the desired place, and the feet at are adjusted towards or from the legsuntil the oil comes level with the bead 18 as may be ascertained by looking downwardly through thetransparent top 20. When this occurs the Oll level is along the line indicated at 21 1n each of the figures. This oil level is just right for each of the burners when they are in operative po sitions. Further, in making the adjustment, the oil level indicating compartment is at the and consequently, any inadvertent overflow during the initial adjustment of the stove will occur at this point and may be readily provided for by able pan or bucket, thus preventing flooding of any portion of the stove or any of the burners even during this initial adjustment.

Although a specific type of burner has been described in connection with this invention, it is apparent that any suitable type can be used.

in the manufacture of this device, the burners and the oil leveling compartment are set by means of suitable gauges at a predetermined distance upwardly from the supply pipe 12. This is most easily accomplished in the manufacture of the stove, and when they have been produced in this manner, it is a simple process to quickly level the stove so that the oil level is correct for each burner, thus securing the maximum efficiency for the stove.

In practicing this invention, it may be desirable, under certain conditions, to provide the adjustn'ient between the stove body and the oil system itself, instead of relying upon the adjustment of the entire stove. Figure 2 shows a scheme whereby this can be readily accomplished. In this figure, the same Construction. of oil system and burners is employed with, however, the difference that the oil system is movable relatively to the stove. For example, threaded pins or screws 22 may be screwed into suitable stationary portions 23 of the stove and may be provided with bearing portions 24 which support the hori zontal pipe 12. Thus by adjusting the screws 21, it is a simple matter to secure the correct line up of each burner with reference to the oil level line 21.

It will be seen that a novel form of oil stove has been provided by this invention in which means are furnished for insuring the correct leveling ofthe oil with reference to each of the burners so that the correct operation of the stove is assured.

I twill be seen further that a very simple arrangement is employed for accomplishing this result.

Although the invention has been described a suite in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.
